Hi, I've seen a remote control used for cranes.
Could you teach me how they works? I believe there are lots of different method doing this.
I want to know the principle of how this works, because, I want to make something phisically happen remotelyby controlling such remote controls like a microcontroller.
hopefully, I want to have 100m range even in the complex buildings.
Car's door lock system mechanism is just what I need. I hope to have longer control range than such car door lock system.
